Predictors of rapid eye movement sleep behavior disorder in patients with Parkinson’s disease based on random forest and decision tree by Wu Chong-Wen, Li Sha-Sha, E. Xu

“…<h4>Background and objectives</h4> Sleep disorders related to Parkinson’s disease (PD) have recently attracted increasing attention, but there are few clinical reports on the correlation of Parkinson’s disease patients with rapid eye movement (REM) sleep behavior disorder (RBD). Therefore, this study conducted a cognitive function examination for Parkinson’s disease patients and discussed the application effect of three algorithms in the screening of influencing factors and risk prediction effects. …”

Odor fear conditioning modifies piriform cortex local field potentials both during conditioning and during post-conditioning sleep. by Dylan C Barnes, Julie Chapuis, Dipesh Chaudhury, Donald A Wilson

“…Naïve rats in their home cages spent 40% of their time in SWS, during which the piriform cortex was significantly hypo-responsive to odor stimulation compared to awake and REM sleep states. Rats trained in the paired odor-shock conditioning paradigm developed enhanced conditioned odor evoked gamma frequency activity in the piriform cortex over the course of training compared to pseudo-conditioned rats. …”
